"The strategic partnership is also a framework to contribute to greater regional stability and growth," it added.

Besides this, two agreements on defence cooperation and loan of artifacts from India to Singapore, two executive programme/operationalisation documents on arts and culture, and white-shipping, and five memorandums of agreement (MoUs) on cyber security, civil aviation, knowledge exchange in the field of planning, urban planning, and combating drug trafficking were also signed.

The second agreement "extends the loan of Indian artifacts to the Asian Civilisations Museum of Singapore".

The operationalisation document on arts and culture is on an "executive programme on cooperation in the fields of the arts, heritage, archives and library" between the Indian and Singaporean governments for the years 2015-2018. The second operationalisation document has been signed following the technical agreement on sharing white-shipping or commercial shipping information about movement of cargo ships between the Indian and Singapore navies signed on July 21, 2015.

"Capacity building, skill upgrading and knowledge development are also identified as areas of cooperation," the statement said.

The fifth MoU was signed between the Town and Country Planning Organisation of India and the Singapore Cooperation Enterprise in Capacity Building in the field of urban planning and governance.
